ASSIGNMENT 1: Physical and Chemical Properties and Changes
1. Look at your notes, text, or Internet to find out what these four terms mean: Physical Property, Chemical Property, Physical Change, Chemical Change
2. Find and copy 4 pictures to your : 1 showing a physical property, 1 showing a chemical property, 1 showing a physical change, 1 showing a chemical change.
3. Place the images on your wiki page under the heading "ASSIGNMENT 1: Physical and Chemical Properties and Changes" and include a 1-2 paragraph exp limy
The two pictures below show butter in two different states of matter. The definition of physical change is a change in the size, shape or state of matter of an object. This means that the example below is a physical change.

Note: each image is worth 3 points and each correct sentence is worth 2 points for a total of 20 points.
NOTE: Below ian example to help guide you. However, you must come up with your own new creative idea, images, explanation.
Chemical Change: The pictures below show the cake changing its chemical balance. The definition of chemical change is the change of substances to different substances. The ingredients get chemically changed to become a completed cake which is a different substance then the original ingredients.

An example of physical property is an unripe banana banana and a ripe banana. The definition of physical property is the change in the material that can be observed like the changing banana color.
An example of chemical property is rain changing a nail to a rusty nail.

The color of this Monte Carlo is a physical property.
A physical change takes place when the car is painted black. The plastic body of the car is still the same substance after the color is changed. We could even melt that plastic into a liquid, and it would still be the same substance because a phase change is also considered a physical change. See the thing is, as long as the chemical composition remains the same, a chemical change has not occurred.
other physical properties include: size, shape, texture, odor, etc.
Corrosivity is a chemical property of acid rain water.
When acid rain water reacts with certain metals, a chemical change takes place (rusting) and the acid rain + metal forms a new substance (rust). Other chemical properties include: flammability, reactivity, pH balance, etc.
Here is the balanced chemical equation showing that Iron, Oxygen, and Water react to form a new substance....rust. 4Fe + 3O2 + 6H2O ---> 4Fe(OH)3
